Title: Fingerprint comparator
IPC: G07C9/00
Filed: 1975-05-01
Abstract: 1506611 Fingerprint comparator H GREEN 1 May 1975 [9 May 1974] 18150/75 Heading G4R [Also in Division G2] A system for automatically comparing fingerprints e.g. for use in verifying cheques or credit cards, has a portion 31 receiving a form such as a cheque or a charge slip on which the customer's fingerprint is affixed on a position to be located behind an aperture 23, in a plate 32 carrying guides 34, 35 for the form. Light from a source 38 is reflected from the fingerprint and passes through aperture 53 to be reflected by mirror 46 into a lens system 47 which is arranged to cause vignetting of the image. The image from the lens system is reflected from mirrors 51, 49 and focused on to a card 16 in a holder 71. The card 16, e.g. a bank signature card, a customer identification card or a credit card carries a fingerprint affixed at its time of issuance. The image of the fingerprint or part of the fingerprint on the form 17 is formed on the fingerprint on the card 16. The holder 71 is rotated over a predetermined range by a drive system 73 to correct a limited degree of angular misalignment which may exist between the fingerprints. Mirrors 49, 51 are oscillated by drive systems 76, 79 so that the image follows a zig-zag scan across the card (Figs. 13, 14, not shown). A photo-cell detects the light reflected from the card and produces a pulse exceeding a predetermined threshold (Fig. 18, not shown) when coincidence is achieved. Light may be reflected from or passed through form 17 (Fig. 5, not shown) or the customer's finger may be pressed on to a window (Fig. 21, not shown) to allow detection of a "live" fingerprint.

Abstract: 1,169,552. Resin impregnated paper laminates. FORMICA INTERNATIONAL Ltd. 26 April, 1967 [26 April, 1966], No. 18214/66. Heading B5N. A method of making resin-impregnated laminates comprises establishing a plurality of bulk storage stacks of sheet material comprising synthetic resin impregnated paper, each stack either comprising a different type of sheet from that (or those) of the other storage stack (or stacks) or comprising different type sheets in a pre-arranged order e.g. a stack of adjacent pairs of impregnated print sheets B and impregnated surface sheets C and a stack of sets of resinimpregnated core sheets A; manually transporting one or more sheets from each storage stack to a movable sheet support member 4 in desired sequence, moving the said member 4 towards a sheet receiving station 6; holding the leading edges of all the sheets on member 4, and withdrawing member 4 so that the held sheets are deposited from member 4 on to the station 6; repeating this operation whereby the successive operations cause the sheets to be stacked at station 6 in a predetermined order required before the conversion of the sheets into laminates; and subsequently removing the stacked sheets from station 6 and consolidating them to form the finished laminate. Platform 1 is rigidly mounted and sheets B situated back to back. Platform 2 is virtually movable and the sets of sheets A are separated by spacer sheets. In making laminates each comprising ten resin-impregnated core sheets A, a resinimpregnated print sheet B and a melaminealdehyde resin-impregnated surface sheet C, a pair of sets of sheets A are manually transferred from 2 to 4 and four top sheets B-C-C-B are manually transferred from 1 to 4, the two top sheets B-C being immediately carried over to 6 and the assembly from 4 laid thereon.

Abstract: 1,201,105. Self-extinguishing phenol-formaldehyde resin foams; aminoplast compositions. COMPAGNIE DE SAINT GOBAIN. 19 April, 1968 [30 May, 1967], No. 18684/68. Headings C3C and C3R.  Fire - resistant phenol - formaldehyde resin foams are made by introducing into an aq. solution containing the resin a surface-active silicone oil, a blowing agent and a nitrogen compound unreactive with uncombined formaldehyde in the resin, stable at the temperature of the process with respect to the blowing agent and releasing on heating a gas which does not support combustion. The nitrogen compound may be a partially condensed aminoplast resin, e.g. the reaction product of formaldehyde with urea, melamine, dicyandiamide or other amine, and optionally phenol, or it may be an ammonium salt, e.g. ammonium sulphite or sulphamate. In examples, phenol was condensed with formaldehyde in aq. solution using as catalyst NaOH, Ba(OH) 2 .8H 2 O or polyvinyl alcohol and then compounded with a silicone oil, trichlorofluoromethane as blowing agent, optionally talc or kieselguhr, and hydrochloric acid and a partially condensed aminoplast resin or ammonium salt.

Abstract: 1424152 Air rifles FORENADE FABRIKSVERKEN 29 April 1974 [4 May 1973] 18702/74 Heading F3C An air rifle has a spring operated piston 1a for firing a projectile and movable inside a casing 4a which also contains a barrel 3 and a displaceable compression cylinder 2, a mechanism comprising a lever 8, pivoted at the rear of the casing, and a draw-bar 6a, connected to the lever, retracting the piston and its spring for subsequent firing by means of a connection between the draw-bar and a front portion 2b of the cylinder comprising a transverse hole in the portion accepting a head 6b of the draw bar with a plug 6c on either side abutting against the casing. The lever 8, of U-shaped cross-section, retracts the portion 2b for retention of the piston 1a by a sear of a firing mechanism in a body attached to the casing 4a engaging a stem 1b. A projectile 5 is loaded via a slot 4b in the casing 4a, a safety catch pivoted in the attached body engaging a slot in the cylinder 2. The lever 8 and the draw bar 6a are retracted to return the cylinder 2 to its forward position after release of the catch, the portion 2b with a frusto-conical end surface engaging a seal 3a in a corresponding surface of the barrel 3. Operation of the firing mechanism releases the piston 1a which upon contact with the portion 2b, by means of a synthetic rubber nose 1c which enters a central passage of the portion, causes air compression for projectile firing. The plugs 6c are of nylon and project slightly from the surface of the portion 2b to provide low friction contact with the casing 4a. The draw bar 6a extends through a longitudinal slot 4c of the casing 4a which ends in a transverse slot beyond the compression position of portion 2b for installation of the plugs 6c and of the head 6b. The lever 8 is held in its retracted position by engagement between a pin 7 extending from the casing 4a and a bent end 9a of a clamp slidable on the lever 8 and spring biased from a grip block 11 fixed to the lever.

Title: Improvements in the manufacture of dialkyl alkylphosphonothionates
Inventor: WEBSTER HAROLD
IPC: C07F9/40
Filed: 1958-06-12
Abstract: A dialkyl alkylphosphonothionate is obtained by forming a mixture of an alkylphosphonous dichloride with elemental sulphur and an alkanol, said alkyl groups and alkanol each containing not more than four carbon atoms, and maintaining said mixture in the liquid state at a temperature in the region of its boiling point whereby the hydrogen chloride produced as the reaction proceeds is liberated in the gaseous phase so that its concentration in the liquid reaction phase remains low.  When the process is carried out batchwise the alcohol is preferably added slowly to a mixture of the alkyl phosphonous dichloride and elemental sulphur at a temperature near to the boiling point of the mixture until the alcohol is present in at least stoichiometric proportions.  When the process is carried out in a continuous manner the alcohol should not be present for any significant time in stoichrometric excess and the process can conveniently be effected by continuously introducing into a reaction vessel containing sulphur the alkyl phosphonous dichloride at a given molar rate and an alkanol at substantially twice the given molar rate, maintaining the reaction vessel filled with the reaction mixture in the liquid state at a temperature in the region of its boiling point and continuously removing from the reaction vessel the reaction product containing dialkyl alkylphosphonothionate.  If desired a stream of inert gas, e.g. nitrogen may be bubbled through the liquid reaction mixture during the process.  Examples are given for the production of dimethyl-, diethyl-, di-n-propyl-, and di-n-butyl-methyl-phosphonothionates the reaction being carried out in each case by adding the appropriate alkanol to a mixture of methylphosphonous dichloride and sulphur flowers under the defined conditions.
